'15 3.5L max tow. 5900 miles on it with a little more than 4000 of that towing. Tow exceptionally well through mountains, flats or wind. Only problem so far was the trailer control module failed on the first trip. Couldn't get 12v power to the TT. Then of course there's the on going paint issues.

The two tone lower was blasted with dirt and in one spot it something laid up against the wet paint then clear coated over....including the dirt. In several areas the red was bleeding through the magnet. That was all on the lower portion. Now I'm getting areas developing in the red that looks like smudges under the clear coat coming from behind the base coat. Obviously bad prep.
Before I get done nearly 75% of my brand new truck will be repainted.

Wow. That's crazy. Mine is a '15 King Ranch and the only issue is a door that is not fitting very well. Took it into service, and adjusting the striker plate didn't help any, so the body shop is going to take it in for a few days while I'm out of town and take care of it. Nothing major, but an annoyance to me.

Had a 2014 F-150 Eco pulling a 30' W/P (10,500+ loaded). Had major sway issues. Didn't have sway issues towing it with a Chevy 2500. Added Air bags, little help. Inflated the tires to max pressure, didn't help. Traded the F150 for a 2015 F250 Diesel. No more sway issues.
If you have sway issues, consider purchasing a re-con Hensley Arrow or a bigger truck.

Wow towing a 30 foot work and play with a f-150? You deserve a purple heart! We were towing on I81 in Virginia going 65 and hit a crosswind towing with my F-350. I now only tow at 55 better safe then sorry. Glad you got a heavy duty truck!

I had a 2012 EcoBoost F150. 2 major issues I had that kept me from hauling a travel trailer of decent size.

1) lack of payload. However I did not have max tow or max payload.

2) complete lack of engine braking. Just driving in the black hills with my family in the cab and cruise control on the truck would drop 2 gears to hold back speed. Imagine with 7-8k behind on a long grade...
